I have an Icon seatpost that came with me Trek 2200 road bike. I know that it is aluminum and its diameter is 27.2mm but I am not sure how to determine the length. I would like to replace it with a Thomson Elite but need to know the length to make sure I buy the right one.
The ICON seatpost is a little bent at the top so what is the right way to measure its length?
You could, of course, buy a longer post than your current one with no problems unless it's so long it hits one of the water bottle braze-ons in the seat tube. Even then, just get out the hacksaw and trim off the excess.
